(Physics) An instrument formed by combining prisms so as to correct the chromatic aberration of the light while linear dimensions of objects seen through the prisms are increased or diminished; called also prism telescope.
I have seen you standing still beneath
rapid clouds at dusk, collecting the light,
drawing the gathered radiance in like breath.
You store it everywhere—as lines, faces,
in crowded notebooks—till it spills out, bright,
new-made. Is this creation, these mixed pieces,
When patched-together, conglomerate, they
emerge like sparks from your hands, lightened
Some men stockpile days
Like weapons, against the cataclysm.
From you, the stored scraps of collected light
leak like constant suns. And what wrought prisms
allow these sudden visions: myself, made
larger and more beautiful, all the bright
fragments ripened and mingled, naked, laid
like webs of stars together? Those saved skies
reflected back to me, mirrors on mirrors,
A tiny universe within your eyes?
